What is the mortality rate of open surgical repair of abdominal aortic aneurysm (AAA)?

Open repair of thoracic and abdominal aortic aneurysms has a mortality of about 4%, with myocardial infarction (MI) being a frequent cause of death.
[14] Preoperative reduction of cardiac risk by means of cardiac investigations and beta blockade may lower mortality. Autologous transfusion techniques (eg, acute normovolemic hemodilution and intraoperative cell salvage) reduce the need for allogeneic blood and the complications associated with open surgery.
